Effect of VC Inhibitor on In-situ Generated WC-reinforced Ni-based Coatings by Laser Cladding AITranslate
Abstract AITranslate
WC-reinforced Ni-based coatings with different VC contents were generated in situ by laser cladding on the surface of H13 steel, and the role of VC inhibitor in refining WC grains and its effects on the hardness and wear resistance of the coatings were studied.The phase, morphology and composition distribution of the coatings were analyzed by XRD,SEM and EDS,respectively.The hardness of the coatings was measured by a microhardness tester, and the wear resistance of the coatings was tested with a friction and wear test machine.The results show that VC has a significant effect on inhibiting the growth of WC grains, and the inhibition effect is the best when the VC content is 10%.The hardness of the coatings with different VC contents is higher than that of the coatings without VC.The coating with 15% VC has the highest hardness.The wear resistance of 10%VC+(W+C)+Ni60 coating,(W+C)+Ni60 coating and Ni60 coating sequentially decreases.VC can hinder the precipitation mechanism of in-situ generated WC grains, resulting in grain refinement.The added VC may also deposit on WC grains, preventing their further growth.An appropriate amount of VC can significantly inhibit the growth of the WC reinforcement phase and improve the hardness and wear resistance of the coatings.
